Select the Proper Resistor
Use 82  resistors if the network operates at 230.4 kbps or if the network
operates at 57.6 kbps, or 115.2 kbps and none of the devices in this table are
present. The maximum number of devices on the network is 32.
Use 150 resistors if the network contains any of the devices in this table, or if
the network operates at 57.6 kbps or 115.2 kbps and you do not require the
network to support more than 16 devices.
